Product Description:

The FC-280P4K0T4H2BNCXXXSXXXXAX is an AC variable-frequency drive manufactured by Danfoss for the VLT FC 280 Midi Drives series. It is intended for cabinet installation in automated production lines where fixed mains power must be converted into controlled motor output. By varying voltage and frequency, the unit helps three-phase induction motors start smoothly, hold commanded speed, and reduce mechanical shock in conveyors, mixers, and ventilation systems. This makes it suitable for equipment that benefits from controlled acceleration and stable running speed. Its compact size also fits mid-power applications that need standard motor control without taking up excessive enclosure space.

The drive provides a continuous motor output of 4.0 kW, which suits small compressors and material-handling axes. In imperial units, that equals 5.0 HP, which is useful where older documentation lists horsepower. Its input stage accepts a three-phase 380-480 VAC supply, allowing direct connection to common industrial power systems in the 400 V class. Because the hardware has no brake chopper, regenerative energy created during rapid deceleration must be handled elsewhere in the system. Operator interaction is shifted to a remote keypad or PC tool because the front cover has no display, which helps reduce panel depth and keeps the front of the unit simple.

Optional protective and expansion elements are omitted on this version. The control board uses an uncoated PCB, so the drive is best suited for clean, dry electrical rooms where corrosive gases are not present. Both modular interface positions, Adaptation A and Adaptation B, are blank and marked no adaptation, so the standard I/O and fieldbus arrangement remain unchanged. Leaving these options out keeps the standard terminal and interface layout in place. The drive is suited to applications that use the base control hardware without added interface modules.
